I generally agree, but I disagree with calling 1 mm IR. That's sort of arguing that the whole THz range is IR which I think is silly (I note that you did not make this up, but it is somewhat commonly used)

I kinda agree 1THz is considered Far IR at 100um, which is a LOT of bandwidth! From working with folks who did Tunnel Junction mixers, I think it's because things start looking particle-like, beyond wave-like at those frequencies.

I guess it's actually called EHF up to 300GHz.
